1.25.2.10 Parameterizable subprogram return jump (RET ...)

Function
Usually, an RET or M17 end of subprogram returns to the program from which the
subprogram was called and processing continues with the program line following the
subprogram call.
However, on the other hand, there are also applications where the program should be
resumed at another position, e.g.:
● Resuming program execution after calling the stock removal cycles in the ISO dialect
● Return to main program from any subprogram level (even after ASUB) for error handling.
● Return jump through several program levels for special applications in compile cycles and
In cases such as these, the RET command is programmed together with "return jump
parameters".
